UNITED STATES PATENT OFFICEe JESSE M. CURTICE AND WILLlAM H. CURTIOE, OF MOUNT STERLING, KY.

CHU RN.

SPECIFTCATION forming art of Letters Patent No. 240,568, dated April 26,1881.

the following to be a full, clear, and exact de- 'sc ription of the invention, such as will enable others skilled in the art to which it pertains to make and'use it, reference being had to the accompanying drawings, which form part of this specification.

Our invention relates to an improvement in I churns, the object bei'ng to provide a simple and efficient device for operating a churndasher; and the invention consists in certain details of construction and combinations of parts, as will hereinafter be described, and

pointed out in the claims;

In the accompanying drawings, Figure l is a view in perspective of our improvement. Fig. 2 is a view in side elevation, showing the churn-dasher raised for the insertion of the body of the churn. Fig. 3 is aplan view of the improvement. Fig. 4 is a detached view of the actuating-lever. Fig. 5 is a detached view, showing renewable bearings for the shaft.

A represents the base, to which is secured the standard B, having two arms, 0 D, east solid therewith. Standard B and arms 0 D are preferably cast hollow, thereby insuring cheapness and lightness in manufacture, and maybe formed of any suitable design and ornamented to suit the taste of the maker.

The lower end of standard B maybe provided with a perforated flange, through which screws are inserted to secure it to the base, or

it may be screwed into the base or secured thereto in any manner desirech E is the dasher-shaft, formed with a sleeve or pulley, F, near its upper end.

Above and below the part F of dasher-shaft E are the journals cm, which fit into the open or halfbearings G G, formed in theouter ends of the arms 0 D. Bearings G G may be formed in the arms, or renewable bearings of Babbitt or other metal may be removably secured within the outer ends of said arms. The elon- 5o gated pulley F of the dasher-shaft fits between thearms, thus supporting the dasher-shaft and Application filed April 7, 1880. (N0 model.)

preventing any end movement of the same while in operation.

H is the actuating-lever. It is provided with a perforated bearing-plate, h, at its center, which fits into a horizontal slot, in, in the upper end of the standard, and is therein retained by apivot, I, inserted in the top of the standard and passed downwardly through the hole 13 in the horizontal bearing-plate.

Upon the opposite ends of the actuatin glever are pivoted the knobs or handles K K, of such form and size as to be easily grasped by the operator. Actuating-lever H is also furnished with the arms L L, to the outer ends of which are secured the pins M M, each having a rounded button-head, m.

N N are straps, each being secured at one end to the sleeve or elongated pulley F on the dasher-sh aft, while their oppositeends are provided with holes a, one or more, to allow the straps to be removably secured to the pins M M on the arms of the actuating-lever.

Straps N N may be made of leather, woven fabric, rawhide, or very thin and flexiblemetal, as thin sheet-brass 5 or, in lieu of straps,

we may use cords or wire, and instead of forming holes in the ends of the straps for attaching them to the arms of the actuating-lever, rings or books may be secured to theends of the straps for such purpose. To compensate for the stretching of the straps, a chain, of two or more links, may be attached to the ends of the straps, and the links of the chain connected with the pins on the arms oil the actuating-lever.

O is the main dasher, it being formed as a continuation of the dasher-shaft, or it may be separately formed and secured to the dashershaft. Dasher O is broad and flat, with square edges 0 To the main dasher O are secured the ovalshaped dasher-blades P 1?, their upper ends being of greater width than their lower ends.

The operation of the device is as. follows: Milk is poured into the churn-body, and the latter inserted in place by unhooking or unbuttoning one of the straps, thereby releasing it from the actuating-arm, and raising the dasher, as illustrated in Fig. 2, then inserting the dasher in the churn-body, and moving the latter in vertical line beneath the dasher-shaft.

The strap is then connected with the arm of the actuating-lever, when all is in readiness for operating the churn. By imparting an oscillating movement to the actuating-lever the dasher-shaft is rapidly rotated in opposite directions, which has the effect of causing the milk to flow around the churn in one direction and then to be suddenly arrested and moved in the opposite direction. The churn-dasher thus strikes the globules of milk with sufficient force to most effectually break them and liberate the cream therefrom.

The curved dasher-blades are graduated in width from their upper to their lower ends, in

order to relieve the churn of any undue load in operation.

The blades are the narrowest at the bottom, as theyare there subjected to the greatest resistance, owing to the pressure exerted thereon by the column of milk in the body of the churn, while the upper ends of the curved dasherblades are made widest, as the upper ends are not subjected to the weight of the milk in the body of the churn.

R is a quill or brush attached to the dashershaft to frighten away flies as the churn is hein g operated.

S is a fan, the handle 8 of which is inserted in a diagonal hole, .9, in the upper end of the dasher-shaft, the fan serving to fan the operator while at work and render the operation of churning both a pleasant and agreeable pastime.

It is evident that many slight changes in details of construction and relative arrangement of parts might be resorted to without departin g from the spirit of our invention, and hence we would have it understood that we do not limit ourselves to the exact construction and firrangement of parts shown and described;

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a standard provided with arms having half-bearin gs in their outer ends, of a dasher-shaft, a horizontal actuating-lever provided with arms L L, and two cords or straps connected at one end with the dasher-shaft and at their opposite ends with said arms, substantially as described.

2. The combination, with the standard having a horizontal slot formed in its upper end, of an actuating-lever provided at its center with a perforated plate, which fits within the slot in the standard, and a pin or bolt extending from the top of the standard downwardly through the perforated plate, substantially as set forth.

In testimony that we claim the foregoing we have hereunto set our hands this 19th day of March, 1880.
